Penne and Valjean are the sixth and seventh puffin chicks to successfully hatch in the National Aquarium’s Sea Cliffs exhibit since 2006. Atlantic puffins generally lay one egg and raise one chick a year.

The two young puffins will remain in their burrows, which mimic the deep burrows that puffins typically use in the wild, for the next 40 or more days. Afterwards, the two new puffin chicks will begin to explore life outside the burrow by making short exploratory trips to the Aquarium’s puffin exhibit.
